Printhead assembly module

In one example, a printhead assembly module includes an upstream row of printheads and a downstream row of printheads. The upstream and downstream rows of printheads are offset from one another such that a printhead in the upstream row extends past the downstream row at one end of the module and a printhead in the downstream row extends past the upstream row at the other end of the module. 在个示例中，打印头组件模块包括上游排打印头和下游排打印头。所述上游排打印头和所述下游排打印头彼此偏移，从而所述上游排中的打印头在所述模块的个端部处延伸超过所述下游排，并且所述下游排中的打印头在所述模块的另端部处延伸超过所述上游排。
